Rectangular Prism (Box) Formulas

Volume

V = l × w × h

Surface Area

SA = 2(lw + lh + wh)

Space Diagonal

d = sqrt(l² + w² + h²)

The space diagonal runs from one corner to the opposite corner through the interior of the box.

计算示例

Box with length 10, width 5, height 3.

  1. Volume = 10 × 5 × 3 = 150
  2. Surface area = 2(50 + 30 + 15) = 2 × 95 = 190
  3. Diagonal = √(100+25+9) = √134 ≈ 11.5758
